LEOPOLDO GALARDI AND LEANDRO PATUZZO, 0F MILAN, ITALY.

PLOWING-MACI-IINE.

Specification of Letters Patent.

Application led February 24, 1916. Serial No. 80,101.

To all 'whom z't may concern:

Be it known that we, LEOPOLDO GALARDI and LEANDRO PATUzzo, engineers, both subjects of the Italian Kingdom, and residents of Milan, Via Durini 18, Italy, have invented certain new and useful Improvements in and Relating to Flowing-Machines, of which the following is a specification.

Our invention relates to certain newimprovements in motor-plows of that class whereby a. frame is combined with an oil engine, plowing means and controlling means.

Object of our invention is an embodiment of parts intended to obtain eiiciency of work, simplicity of construction and improved output.

In the annexed drawings are represented by way of example two forms of construction of our said invention. l

Figure 1 is an elevational view of a motorplow of great power.

Fig. -2 is a plan view of same. Figs. 3 and 4 represent respectively a sid elevational view of a second form of construction and a plan of same.

Figs. 5*6-7-8-91011' represent certain details of construction as will be more clearly described hereafter.

The form of construction represented in Figs. 3 4- comprises the tractor-frame consisting of beams 2 3-, uprights -4 and stays -5-6-, duly riveted to one another to form a rigid system.

On a vplatform provided at the forward part of said tractor-frame, is mounted and fixed the oil-engine -1-.

To the rear ends of the upper beams 2- are rigidly connected the arms -7- provided at their ends with handles -8-.

A battery of plows, each of which comprises mold board -9- and share l0- is swung on a frame consisting of bars -11- projecting rearward from beams -12-. Said beams 12 are pivotally connected to the lower part -25-' of the tractor frame, 'b'y means of pivots Q4- longitudinal slots in said beams and holes 26,

in said tractor-frame.

Several holes -26'- are provided in order to connect the beams -12- at different positions.

' The supporting frame for the battery of plows is pivotally connected at 14- to aA rack 15 which function is toshift the plows vertically and to vary the angle of incidence of the shares by means of hand operations and a clutch device that will be described hereafter.

The progressive motion of the tractor is obtained by means of a drum -16- pro` vided with radial blades -17- and mounted on a transverse aXle 23-.

The blades may have different shape, as shown by Figs. -5-6-7-10 but they all have the effect of engaging the ground in order to produce suiiicient reaction for the progressive motion.

The way how the blades -17- are connected to the drum -16- is shown by the Figs. -5-6-7-810-11- which show different views and sections of the drum.

Each blade has a pivot-projection, 19- and an eyed lug -20-, to said projection 19- and to -said lug 20- correspond respectively hole 21 laterally on drum -16- and eyed lug 22,- on the opposite side of drum -16-.

For the connection ofthe blade to the drum, pivot-projection 19- enters hole -21- and the two eyed-lugs 20-22 are locked together.

18 are slots on the surface of drum -16- and which give .passage to the blades *17 18 is a T-like bar to cover the slots 18 when the tractor is driven on a road 'and consequently the blades 17- have to be removed.

In order to shift the plows vertically a clutching device is provided consisting of a rectangular member -30- in which is longitudinally arranged a slidable link -31 which extends through the front and rear sides -32-33- of saidsupporting member -30; -28-29- are supporting bars for member -30.

The rack *15* passes through said supporting member 30 and through the enlarged portion 34 of link 31 and normally Patented Dec. 16, 1919.r

engages a transverse rod 37-A Xed on press downward or pull upward arms -7 to vertically move member 30 and link 31 relatively to rack 1b, and finally release lever -38- to have the rack -15- fixed in its new relative position; it will be understood, that the mentioned operation, will vertically adjust the plows and vary the angle of incidence of the plows while the tractor is kept horizontal.

The driving means of drum A6- comprise: belt 41 stretched between enginepulley 4Q- and fiXed-and-loose pulleys i3-4% mounted on beam -2-.. The shaft of pulleys -43-44- bears gearwheel l5- gearing with pinion -46- and the axle of pinion 4G- bears sprocketwheel -47- connected to sprocket-wheel -48 on drum -16- by means of a chain 4l/ It is worth mentioning that the distribution of parts is such as to have the machine completely balanced on the axle -23- of drum -16-; moreover the driven sprocketwheel -47- is mounted on the same part of the machine, in respect of the axle -23-, as the plows.

Such position secures a pressure on the plows while the engine is driving the plows.

Lever -53- wire -54-, lever -50-, connecting rod dlthat slides in bridge -52 constitute a shifting device to remove the belt -41- from pulley -43- to loose pulley and vice-versa.

-55- is a lateral wheel as is generally used with plows which have to work on hilly fields.

In the form of construction represented by Fig. l 2- the engine is directly coupled to the drum -57- by means of a sprocketcha-in --58- mounted between wheels -59-60-- The progressing drum is in this case constituted by a disk o7- provided with laterally projecting blades 6l- The fore-beam -63-- of the plow (54- is connected to the axle -65- of drums BG- which roll on the ground and support the machine.

Having now particularly described and ascertained our invention and the manner in which the same should be performed we declare that what we claim is:V

l. The combination with a supporting drum, of a framework provided with handles supported by said drum and manually movable about the axis thereof, a plow carrying member pivotally connected to said framework atthe rear of said drum axis, plowing tools connected to the plow carrying member, and mechanism forY connecting the framework and plow carrying member in adjusted relationshi) determined by the manual movement of t e framework about the drum axis, said mechanism comprising a rack connected to said member, means carried by the framework normally engaging said rack, and means operable to eect disengagement of said rack and to effect reengagement thereof after said manual movement of the framework relatively to the rack.

2. The combination as defined by claim l, in which an operating member is mounted on one of said handles and is connected to the last named means.

3. The combination as defined by claim l, in which a stationary member is fixed to the framework and is normally engaged by said rack and a rack disengaging member is slida'bly mounted on said framework.

ln testimony whereof we have atlixed our signatures in presence of two witnesses.
